Your link is misaligned. Check the configuration on the other side - it 

should provide the master clock according to your system.conf

Thanks for your time. I have put sigchan after the group definition, 

but the result was the same. I notice in the logs (before and after the 

modification you suggested) the following message:

Huh?! chan_dahdi.c: [11] Huh?! Got FISU in link state 1. I've searched 

the web but I couldn't find the meaning of this message.

Hello,
put sigchan after the group definition:

group=1
cicbeginswith=1
channel => 1-15
cicbeginswith=17
channel => 17-31
sigchan=16

for now remove the slc line and check the configuration on the other
side: if it is configured to use different slc, then add it before
sigchan
